Just found this from our BP Fuel distributor in Australia. Should help with questions about when what why and how to look after your fuel on your trike. Remember this is written for Australia so please consider the RON octane rating and the seasons vs months where it applies.

Now discuss. Hope it helps someone else.

Thank you CB !! Excellent find for us. Some intriguing quotes:
"It is not possible to provide a foolproof strategy for engines that are used only intermittently,however the following principles help. ..."

"Always keep the tank half full to stop water vapour from being sucked in and condensing."
HALF FULL ?? I thought you were supposed to fill it to leave no room for air that could condense?

"... octane can actually increase with time but this octane is not available for high revving conditions..."

The half full surprised me too.

RE "Half Full": The only thing I could think of is that GA aircraft are advised to keep the tanks FULL to avoid airspace which could contain moisture which could condense to water. 100LL is more stable however, so storage is not as much of an issue.
In my trike, I actually like to keep the tanks less filled when not using so that I can put MORE fresh fuel in to immediately fly on. I do have a water inspection port on the bottom of the tank I use AND I have a Racor Fuel/Water separator / filter ...
Maybe the thinking on the half full tank was that you'd have half as much air to condense, but could still put in half a tank of fresh????

Good find. Also interesting is the uv comment as in AU we had concerns about shell ultra degradation due to uv, looks like it may apply to all brands. - airborne trikes have translucent tanks.
